On-grid solution(Rapid Shutdown): Convert the DC from solar panels into AC with the same voltage, frequency, and phase as the grid electricity,and transmit the power to the grid, According to the safety requirements, install PV rapid shutdown device between PV modules and inverter, which can quickly cut off the DC high voltage among modules, the high dc voltage between photovoltaic module and grid-connected inverter,In the vicinity of the inverter, it is necessary to install (internal/external) isolatior to quickly turn off the inverter. In order to ensure the safety and reliability of on-grid solution, a distribution box is required to meet the requirements of distribution systems.
On-grid solution(Micro Inverter): Convert the DC from solar panels into AC with the same voltage,frequency, and phase as the grid electricity,and transmit the power to the grid. Use micro-inverter to replace traditional string inverter, module-level MPPT, maximize the photovoltaic power generation efficiency of the system. At the same time, the low input DC voltage makes the system safer.
Optical Storage Solution(Rapid Shutdown): Use an inverter to convert DC, control battery charge or discharge period, and balance the requirement of local loads. According to the safety requirements, install PV rapid shutdown device between PV modules and inverter, which can quickly cut off the DC high voltage among modules, the high dc voltage between photovoltaic module and grid-connected inverter,In the vicinity of the inverter, it is necessary to install (internal/external) isolatior to quickly turn off the inverter. The battery can convert excess ac into direct current for storage, and then convert it into alternating current for discharge when the power is insufficient, and the charging and discharging processes need to be protected. Non-polarity miniature circuit breaker can realize bidirectional protection of cable.
Optical storage solution(Micro Inverter): The combination of photovoltaic power generation system and energy storage system, convert solar energy into electrical energy, and achieve the balance of local loads through the battery charge or discharge. Use micro-inverter to replace traditional string inverter, module-level MPPT, maximize the power generation efficiency of the photovoltaic power generation system. At the same time, the low input DC voltage makes the system safer. The battery can convert excess ac into direct current for storage, and then convert it into alternating current for discharge when the power is insufficient, and the charging and discharging processes need to be protected. Non-polarity miniature circuit breaker can realize bidirectional protection of cable.
Energy Storage System: Can be connected to the power grid as an independent system, and can play the role of peak shaving and valley filling reactive power compensation for the power grid.The battery can convert excess ac into direct current for storage, and then convert it into alternating current for discharge when the power is insufficient, and the charging and discharging processes need to be protected. Non-polarity miniature circuit breaker can realize bidirectional protection of cable. By changing the distance between the dynamic and static contacts and increasing the method of the arc ignition coil, the arc can smoothly enter the arc extinguishing chamber, thereby cutting off the fault. In addition, an AC distribution box is required to meet the requirements of the power distribution system.
